Cold Roll Strip Hastelloy C276 Corrosion Resistant Alloy
Hastelloy C276 alloy is one of the most well known corrosion
resistant alloys, and that was appeared in 1965,after 1970 using
off-furnace refining (AOD,VOD) production to obtain ultra-low
carbon and high purity. In order to reduce the disadvantages of
consolidation heat treatment after welding or thermoforming, except
for reducing carbon content, also the silicon content in the alloy
reducing to 0.08%. Reducing the carbon content can reduce the
amount of the carbon out quantity in the alloys, reducing the
silicon content could reduce the amount of precipitation between
metals in alloys, so that can achieve the purpose of increasing
intercorrosion resistance of alloy. At the same time, the
plasticity, toughness and processing properties of the alloy were
improved.
Like other nickel alloys, it is ductile, easy to form and weld, and
possesses exceptional resistance to stress corrosion cracking in
chloride-bearing solutions (a form of degradation to which the
austenitic stainless steels are prone). With its high chromium and
molybdenum contents, it is able to withstand both oxidizing and
non-oxidizing acids, and exhibits outstanding resistance to pitting
and crevice attack in the presence of chlorides and other halides.
Furthermore, it is very resistant to sulfide stress cracking and
stress corrosion cracking in sour, oilfield environments.

Advantages of Hastelloy C276
Excellent corrosion resistance in reducing environments
Exceptional resistance to strong solutions of oxidizing salts, such
as ferric and cupric chlorides
High nickel and molybdenum contents providing good corrosion
resistance in reducing environments
Low carbon content which minimizes grain-boundary carbide
precipitation during welding to maintain resistance to corrosion in
heat-affected zones of welded joints
Resistance to localized corrosion such as pitting and
stress-corrosion cracking
One of few materials to withstand the corrosive effects of wet
chlorine gas, hypochlorite and chlorine dioxide
